Are you by chance using any FREADSEEK calls as well?

There are documented problems with FREADSEEK and 6.5/7.0 OS.

Some additional analysis shows that our long-running MRP job is spending
most of its time in a subroutine where it does a lot of FLOCK - FREADDIR -
FWRITEDIR - FUNLOCK processing.  The long run time might be caused
by the impact of the "large files" code added in 6.5 and 7.0.
Perhaps a design done in the 70's for a Series 33 isn't the best design for
an application running on an N-class machine under 7.0.
